CHANGE ORDER
Garth Road Reconstruction Project - Phase A & B
5/29/2026
Harper Brother Construction, LLC
Kimley-Horn & Associates, Inc
Explanation:
This change order encompasses the following:
Change Order No.:
CoB Project No.:
P.O. No..
RDWY1901
4260009
This change order adds a new item to compensate the contractor (Harper Brothers, LLC) for the removal of stockpiled asbestos concrete drainage
pipe from a prior contract, that is currently stored along West Archer Road. It also establishes a new cement treated base item to replace the lime
treated subgrade items previously under Line Items 27 and 28. It also adds a new precast junction box item and revises existing drainage items
associated with the changes resulting from Reqest for Information (RFI) #19. In addition, it adds compensation to the contractor for the elimination
of existing pavement markings throughout the project limits. No contract time adjustments will be made as part of this change order.
The project provides for the full reconstruction and widening of the Garth Road facility consisting of grading, lime -treated subgrade, cement -
treated base, asphalt pavement, continuous reinforced concrete pavement, inlets, storm sewers, culverts, illumination, signals, signing, and
pavement markings, The contractor, Harper Brothers Construction, LLC ("HB"), remains on -site and continues to perform the contract according to
the plans and the TxDOT 2024 Standard Specifications, TxDOT controlling CSJ is 0912-72-359. All change order work is within the project limits.
1. Disposal of Asbestos -Cement Waterline Pipe
At the beginning of the project, Harper Brothers Construction, LLC ("HB") identified a stockpile of asbestos cement ("A/C") waterline pipe located
along West Archer Road, near the project field office at 1210 West Archer Road. The City confirmed that this material was left in place under a
previous contract that was terminated prior to the start of the HB contract for Garth Road Project, Phase A & B. As such, the stockpiled A/C pipe
was not included in the original contract scope or associated bid quantities for the current project.
While the Garth Road Project does include contract items for the removal and disposal of A/C waterline pipe encountered as part of the planned
construction work, the existing stockpiled material was separate from those anticipated quantities and was not accounted for in the original HB
contract.
Because the removal and disposal of A/C material requires a specialized contractor licensed to handle hazardous materials, the City determined that
the most efficient and expedient approach was to add the disposal of this existing stockpiled material to the current HB contract. Incorporating this
additional work into the project will allow the material to be removed more quickly and in coordination with ongoing project activities, while
ensuring proper handling and disposal in accordance with applicable requirements.
The City requested pricing from HB on March 10, 2026, and received a response on April 13, 2026. Upon review, the City has determined the
submitted pricing to be fair and reasonable for the proposed scope of work.
Harper Brothers will remove all A/C pipe currently stored along West Archer Road in accordance with the safety practices outlined in the American
Water Works Association publication "Work Practices for A/C Pipe." (Line Item #240. 1). All recommended procedures within this publication
must be strictly followed. Compensation for this work will be made on a lump sum basis for the complete disposal of all asbestos cement pipe
currently stored along West Archer Road.
2. Cement Treated Base (CTB) in Lieu of Lime treated Subgrade (LTS)
The proposed roadway typical section depicted in the plans consists of a 6-inch lime treated subgrade (LTS), a 6-inch cement treated base (CTB), a
l-inch asphalt bond breaker, an 1 1-inch continuously reinforced concrete pavement (CROP), and Cement Stabilized Backfill (Line Item 62). These
components are quantified and incorporated into the overall estimated quantities for the roadway items. However, plan sheet 13 includes a typical
section applicable to all areas where the top of the proposed reinforced box culverts (RCB) extends into the planned 6-inch LTS. In these locations.
the typical section indicates that the LTS is to be omitted over the RCB and for 10 feet on either side, and instead replaced with a thickened section
of cement treated base. Furthermore, this detail specifies that any additional CTB required shall be considered subsidiary to Line Items 68 & 69.
Construction 1 of D16 Revised 5/2026
After reviewing the standard section and mapping of its application on the project plans, it was observed that only a narrow area along the center of
the roadway is not covered by this detail. This segment, which varies in width, is generally estimated to be between 1 I and 15 feet wide. Due to the
limited quantity and logistical challenges associated with LTS placement, Harper Brothers Construction submitted a request for approval to use
CTB instead of LTS throughout the project limits. This change eliminates all LTS installation from the scope of the project and establishes a
revised typical section consisting of two 6-inch layers of CTB, a 1-inch bond breaker, and an 1 l -inch CRCP. The city reviewed this request and has
approved the proposal.
To comply with TxDOT testing requirements and maintain accurate project documentation, the city will issue a change order to replace the two
Line Items (27 & 28) related to LTS installation with one new line item for 6" cement treated base (Line Item 29.1). The unit cost is set to match
the Square Yard (SY) cost of lime treated subgrade, as this change to the typical section is intended for contractor convenience rather than
correcting any issues in the plans that would prevent installation as originally specified.
3. Drainage Revisions Associated with Reaest for Information #19 (RFI #19)
The original storm sewer plan sheets showed Trunk Lines B and D connecting directly into the proposed cross culvert at Independence Boulevard
without the use ofjunction boxes. However, no connection detail was provided in the plans for these tie-ins. As a result, the contractor submitted
RFI #19 requesting clarification of the Engineer of Record's (EOR) intent and asking that a connection detail be provided. At the time RFI #19 was
submitted, the contractor had already begun installation of the Independence Boulevard cross culvert and requested an expedited response in order
to avoid impacts to production. Due to the time required to fully design and detail the proposed connections, the FOR determined that the original
concept could not be completed within the contractor's schedule. To prevent delays to ongoing work, the FOR elected to revise the design and
utilize precast junction boxes at the two Phase 1 connection locations associated with Trunk Lines B and D.
The revised plan sheets were issued to the contractor as part of the official RFI # 19 response on April 5, 2026. Included in the revisions was the
elimination of the proposed cross connection at Sta. 182+00 between Trunk Lines C and D. This connection was removed in an effort to help offset
costs associated with the addition of the junction boxes.
Where applicable, existing contract items will be utilized to compensate for the adjustments associated with RFI #19 (Line Items 68,69,83).
However, a new contract item will need to be established for the proposed 13' x 13' junction box (Line Item 84.5), as no comparable item currently
exists within the contract. The contractor subsequently submitted a detailed cost breakdown outlining the labor, equipment, and materials required
for installation of the proposed 13' x 13' junction box. After review, the City has determined the submitted pricing to be fair and reasonable for the
scope of work involved.
4. Elimination of Existing Pavement Markings Throughout the Project Limits
After completion of the traffic switch into the Phase 1 Step 3/4 configuration striping, the subcontractor, Traffic Signs & Lines (TS&L), notified the
prime contractor that the existing contract did not include compensation for the removal of existing pavement markings required to facilitate the
traffic transition. The work proceeded while field personnel monitored and documented the removal activities to ensure accurate records of the
work performed and quantities involved were maintained. Following completion of the traffic switch, TS&L submitted a formal change order
request seeking the addition of contract pay items specifically associated with the removal of existing pavement markings. The proposed change
order and associated quantities were subsequently reviewed by the Engineer of Record (EOR), Kimley-Horn, to verify the legitimacy and extent of
the additional work.
As part of this review process, the FOR not only evaluated the quantities submitted by TS&L for the recently completed Phase 1 Step 3/4 traffic
switch, but also performed a comprehensive forward -looking quantity analysis for future traffic control phases anticipated throughout the project.
This expanded review ensured that all anticipated pavement marking removal quantities associated with upcoming traffic switches were identified
and incorporated in advance, reducing the likelihood of future discrepancies or repeated contract modifications. The final approved quantities
therefore accounted for both the work already completed during the Phase 1 Step 3/4 switch and the anticipated removals required for subsequent
traffic phase transitions.
The city reviewed the quantities as well as the submitted pricing from the sub -contractor (TS&L) and has determined the submitted pricing to be
fair and reasonable for the proposed scope of work (Line Items 21.1, 21.2. 21.3, 21.4, 21.5).
The unit cost established as part of this change order is full compensation for the elimination method used and materials, equipment, tools, labor,
and incidentals. Removal of the Raised Pavement Makers (RPMs) is included in the contractors pricing, and will not be an additional cost.

Question Question from Brian Hancock Harper Brothers Construction, LLC on Monday, Mar 30, 2026 at 11:59 AM EDT
At the intersection of Independence, the RCB at the cross culvert is connecting to a perpendicular run that travels south to
north. This RCB connection is not shown in the details and according to the manufacturer is not feasible with RCB alone due
to the wall thickness and length of the RCB units. Harper Brothers recommends the installation of junction boxes to combine
the RCB at the point of intersection. This problem exists in multiple areas on this segment of the drainage.

Official Response
Response from Tyler Barrows Kimley-Horn and Associates on Sunday, Apr 5, 2026 at 02:38 PM EDT
See attached revised plan sheets and additional junction box details for the connections on the West side of Garth Road. An
11'x11' junction box is to be added to the 8'x4' RCB connection and a 13'x13' Junction box is to be added at the 10'x5'
connection. The 8'x4' RCB is no longer required at station 182+00 and has been removed. A cost breakdown has been
provided minus the cost for the additional 13'x13' junction box as this does not have a unit cost associated with it yet. We will
issue connection details for the connections on the East side of Garth at a later time.

Yes, this will have to be a change order. I reviewed the plans and didn't see where we noted that it was subsidiary
to other items.

Tyler,
Just to confirm, I assume by you providing the updated CO quantities that you would agree that this would
constitute a CO? I have gone through them but I just wanted to be sure there is no where in the pans that would
point to this work being incidental?

Tyler/Danielle,
Please see the attached change order request for removal of existing striping from the recent traffic switch into the
Phase 1, Step 3/4 configuration.
reviewed the plans and specs and didn't see anything indicating this work is subsidiary to another item. The
general notes reference Item 677 (Eliminating Existing Pavement Markings & Markers), but there's no direction on
how it's to be paid and no bid item included in the contract.
The contractor's pricing comes out to $8,532.15 for the removals completed so far. If we agree this work should be
paid and isn't subsidiary, we'll also need to include quantities for upcoming traffic switches. Per the 2024 TxDOT
specs, Item 677 is a plans quantity item, so we'll need to review the upcoming TCP, determine a total quantity, and
apply the unit price to build out the final change order.
Let me know what you think.
Thanks,
Bryce Watson, P.E.

Eliminating Existing Pavement Marking and Markers
2024 Specifications

Item 677 rM
EliminatingExistingPavement Markings MarkersJ�Te.
gpTianspoRafion
1. DESCRIPTION
Eliminate existing pavement markings and raised pavement markers (RPMs).
2. MATERIALS
Furnish surface treatment materials in accordance with the following Items.
■ Item 300, "Asphalts, Oils, and Emulsions'
■ Item 302, "Aggregates for Surface Treatments"
■ Item 315, "Fog Seal'
■ Item 316, "Seal Coat'
Use approved patching materials for repairing damaged surfaces.
Use a commercial abrasive blasting medium capable of producing the specified surface cleanliness. Use
potable water when water is required.
3. EQUIPMENT
Furnish and maintain equipment in good working condition. Use moisture and oil traps in air compression
equipment to remove all contaminants from the blasting air and prevent the deposition of moisture, oil, or
other contaminants on the roadway surface.
4. CONSTRUCTION
Eliminate existing pavement markings and markers on both concrete and asphaltic surfaces such that color
and texture contrast of the removed area and surrounding pavement surface will be held to a minimum.
Remove all markings and markers with minimal damage to the roadway to the satisfaction of the Engineer.
Repair damage to asphaltic surfaces such as spalling and shelling greater than 1i8 in, deep resulting from
the removal of pavement markings and markers. Dispose of markers in conformance with federal, state, and
local regulations. Use any of the following methods unless otherwise shown on the plans. Refer to the
Pavement Marking Handbook for additional information on removal types and best practices.
4.1. Surface Treatment Method. Apply surface treatment material at the rates shown on the plans, or as
directed. Place a surface treatment at least 2 ft. wide to cover the existing marking. Place a surface
treatment, thin overlay, or microsurfacing at least one lane in width in areas where directional changes of
traffic are involved or other areas as directed.
4.2. Burn Method. Use an approved burning method. For thermoplastic pavement markings or prefabricated
pavement markings, heat may be applied to remove the bulk of the marking material before blast cleaning.
When using heat, avoid spalling pavement surfaces. Ensure the burning heads are not left in one place too
long to prevent pavement damage. Sweeping or light blast cleaning may be used to remove minor residue.
4.3. Blasting Method. Use a blasting method such as high-pressure water blasting, abrasive blasting, water
abrasive blasting, shot blasting, slurry blasting, water -injected abrasive blasting, or brush blasting as
approved. Use high-pressure water blasting for removal of pavement markings for lane shifts on concrete
surfaces.
920
2024 Specifications 677
4.4. Mechanical Method. Use any mechanical method except grinding. Do not use flail milling on grooved
concrete or porous asphalt.
4.5. Corrective Actions. Whenever removed markings on asphalt surfaces continue to simulate pavement
markings to an extent determined by the Engineer to cause driver confusion, apply a fog seal or slurry at
least 2 ft. wide over the area where pavement markings were removed as approved.
5. MEASUREMENT
This Item will be measured by each word, symbol, or shape eliminated; by the foot of marking eliminated; or
by any other unit shown on the plans.
This is a plans quantity measurement Item. The quantity to be paid is the quantity shown in the proposal,
unless modified by Article 9.2., "Plans Quantity Measurement." Additional measurements or calculations will
be made if adjustments of quantities are required.
6. PAYMENT
The work performed and materials furnished in accordance with this Item and measured as provided under
"Measurement" will be paid for at the unit price bid for "Eliminating Existing Pavement Markings and Markers"
of the type and width as applicable. This price is full compensation for the elimination method used and
materials, equipment, tools, labor, and incidentals. Removal of RPMs will not be paid for directly, but will be
subsidiary to pertinent Items.
